To aZZ whom t may concern.'

Be it known that l, VILLIAM D..MO0N, a citizen of the United States,residing at Blocton, in the county of Bibb and State of Alabama, haveinvented certain new and useful Improvements in SafetyStops for Mine-Cars, of which the following is a'specifcation, reference being had tothe accompanying drawings. i

`This invention relates to improvements in safety devices for mine carsor cars moving upon inclined surfaces and the object of the invention isto provide means whereby the car may be stopped or derailed when upon anincline and if the hoisting cable breaks or for any other reason the carmoves backward. I

A further obj ect of the invention is to provide drag bars adapted tobel detachably mounted upon the draw bar of the car so that the drag barattachment may be shifted to the rear end of the car or the last car ofa train of cars.

A further object is to provide an attachment of this character whereinthe drag bars cannot get under the car in casey of a wreck and in whichthe drag bars are so formed that they can never rise too high nor extendout too far to either side.

A further object is to provide a construction of this character in whichthe drag bars will straddle the usual rollers on which the `cable issupported so as not to foul the cable.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein-Figure l is a plan view showing my drag i bar'applied to a mining` car;

Fig. 2 is a side elevation of the structure shown in Fig. l;

Fig. 3 is a longitudinal sectional view through a portion of the drawbar and through the socket member 10; and

Fig. 4 is a section on the line 4 4 of Fig. 3.

Referring to these figures A designates the ordinary track upon whichthe cars are supposed to run, this track being at an incline. The trackis supported upon the usual ties B carrying the usual rollers C. All ofthese parts are ordinarily found in tram roads for mines. Operating uponthe rails A is the car D or train of cars. Each of the cars D isprovided with the usual draw bar E.

Specification of Letters Patent.

Patented Feb; 27, 191'?.

My invention consists of a .rectangular casing l0 which is open atopposite ends and isadapted at one end to fit over the 'draw bar E andbe held in place thereon by the pin 11 which passes throughperforations'in the upper and lower walls of the casing 10.

The side walls of the casing 10 are formed with openings for the'passageof a transverse pivot pin 12 and pivotally mounted upon this pivot pin12 are the drag bars 13.` These bars extend outward and laterally at asu'iicient inclination to a vertical plane-passing through the axis ofthe cars so that the eX- tremities of the barswill not strike therollers C but will travel fon each side of these. rollers. its rear endis cut away as at 14, the purpose of which'is to allow the drag bars toincline downward at a proper angle so as to ride over the ties. Inasmuchas the casing 10 projects beyond the forward edge o-f the cut Lawayportion 14, it is obvious that the drag bars will be prevented fro-1nrising too high l and that the side walls of the casing prevent the dragbars from spreading toomuch.

lThe under face of thecasing 10 at r.The boX or casing l0 ismade ofmaterial y which may be bent and the drag bars may also be bent and inthis way the device may be made adjustable to`4 any height of car. Thedrag bars 13 are-always dragged lightly over the surface of the ties andycan never get too high or too far out to either side. The ends of thedrag bars travel laterally of the outer ends of the rollers C but insideof the rails.

With a drag constructed in accordance with this invention, the drag barscan never get under the car incase of wreck because the box or casingl() will only Vpermit the drag bars to be depressed to a certain angleand further than this they cannot move unless something breaks. Thedrag, as it is obvious from the drawings, is at all times in place to doits work and cannot get out of place. It will not knock the rollers Cout of position and permits the drag rope or cable by which the car ismoved to travel on the rollers and this keeps the rope from dragging onthe ties.

Immediately upon thetrip breaking and the car starting to run backwarddown the slope, this drag will either stop the cars on the rails orderail the rear' carto which it is attached and the derailed rear carwill stop all the remainder of the cars of the train loV and keep themfrom being broken up, keep the timbers of the mine from being knockedout, and prevent casualties t0 the men Yand mules.

lt will be readily removed from one car and placed upon another and thatit may be readily removed when the car is moving down a slope. OfcourseV it is ob vioiis that the drag bars may be made as heavy asdesired but they should not be of greater strength than the draw bar. ltwill be seen from the drawings that the drag bars 13 are slightly curveddownward with points beveled or made sharp so that they will easilystick either in wood Or dirt. twill be seen that the drag bars will notcome in contact with the rollers C not only because the drag bars arespaced at their'rear ends aV distance greater than the length of therails but for the reason that the drag bars will pass over anything thatthe car axles will.

VHaving described my invention, what l claim is:

l. A safety attachment for mining cars comprising a casing adapted toreceive and engage with the rear end of a draw bar, and a drag barpivotally mounted in the rear end of the casing.

2. A safety attachment ior mining cars comprising a socket memberadapted to fit over the end of a draw bar and be detachably connectedtherewith, and rearwardly divergent drag bars pivotallymounted forvertical movement in the other end of the socket member. Y

3. A safety attachment Vfor mining cars comprising a socket memberadapted to fit over the end of a draw bar and be detach- Copies of thispatent may be obtained for be seen that my attachment mayV ablyconnected therewith7 and rearwardly divergent drag bars pivotallymounted for Vvertical movement in the other end of the socket member,the under side of the socket member being cut away at lits rear end topermit the drag bars to extend downward and rearward, the top of thesocket member preventing too great upward movement of the Vdrag bars. Y

Safety attachment for mining cais comprising a socket member adapted tobe disposed over the end of a'draw bar and det-.reliably connectedtherewith', and' rearwardly divergent Vdrag bars pivotally mounted inthe rear end of the socket member for independent vertical movement.

5. AV safety attachment for mining cars comprising a socket memberrectangular in cross section and relatively shallow and adapted to bedisposed over and engaged with the rear end of a draw bar, the socketmember having perforations in its upper and lower walls for thereception of an at- Y taching pin to the draw bar, the bottom oi? thesocket member at its rear end being cut away so as to be shorter thanthe top and the side walls of the socket member at its rear end beingperforated, a pivot pin passing through the last named perforations, anddivergently disposed drag bars pivoted upon said pin and having limitedvertical movement within the socket member.

In testimony whereoil I hereunto aiiix my signature in the presence oftwo witnesses.
